From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Acft tipped over on its side on landing. Long Beach, CA (.4)during the autorotation, the student allowed the aircraft to descend lower than he had previously and was instructed to increase his flare. The student said he believed this now meant that they would be executing a full touchdown autorotation; however, he did not confirm this with the instructor. As he leveled the aircraft a sink rate developed. The instructor reached for the controls to reapply throttle but did not announce his intention. The student held the throttle at idle and pulled pitch delaying the instructor's efforts with his tight grip on the controls. The aircraft fell though, landing hard on the left skid. The aircraft bounced and rolled onto its left side. The instructor had not briefed the student on the performance standards before executing the maneuver, nor had he announced the method to be used for a positive transfer of controls. The student did not verify the instructor's performance standards, recognize the excessive rate of descent, or relinquish control of the throttle.
